While there is absolutely NO WAY I would transport Rascal like this, I can think of much worse transports I have seen. At least they have a wind break on top of the cab. I'd have made the sides another 18 inches or so higher, tied him a tad bit shorter, and I'd be driving Miss Daisy as far as speed goes. I hope he is on a nice rubber pad for traction.
This puts me in mind of the photo of the guy on a moped with the donkey LOL
At least the guy put sides on it and a block from the wind. When I bought my horse 15 years ago I bought her from this really very back road kind of guy. One of his "selling points" when I went to look at her was "shes so calm! I drove her down the road in the back of my pickup truck the other day!" There are people out there that do this, and while I don't consider it safe, unfortunately you can't stop stupid.
